I have a Macbook from late 2008. The aluminum, 2.4 ghz, 250 gb, 2 gigs of ram. It is in perfect condition. I bought it for 50. It is now 15 months old. You can now, buy it brand new for 1200. How much would be fair to sell it to one of my friends?

I’ll buy the Intel Core i3 2100 processor.

what is mean the ‘ Instruction Set‎‎64-bit‎’ ?
And can I have memory of 2 GBs 1066MHz DDR3,Speed PC3-8500,Latency CL7?
And what you think about this processor?

So i just bought a Macbook Pro: 2.66 GHz, 4GB of memory, 500 GB HD, upgraded Serial ATA Drive @ 7200 rpm. I know there are limitations and advantages to using a Mac, but I am a first time buyer. I would just like to know what games my Mac can play and how I am to know if they will work before I buy.

MBP Unibody 15" 2.4 GHz (Late 2008)
Are the other parts worth a percentage of each new equivalent’s price?
Should I sell the MacBook Pro altogether or individually by parts?
